The Forest Service manages winter uses to protect National Forest System (NFS) resources and to provide a range of opportunities for motorized and non-motorized recreation. In 2005, the agency regulated winter motorized use as a discretionary activity under its regulations for Use by Over-Snow Vehicles. Consistent with a court order dated March 29, 2013, the United States Department of Agriculture (the Department) amends the Department's travel management rule (TMR) to require designation of roads, trails, and areas on NFS lands to provide for over-snow vehicle (OSV) use. An over-snow vehicle is defined as “a motor vehicle that is designed for use over snow and that runs on a track and/or a ski or skis, while in use over snow”. The Responsible Official will establish a system of routes and areas to provide for over-snow vehicle use. The regulations will continue to exempt over-snow vehicle use from the travel management rule, which provides for designation of a system of routes and areas for other types of motor vehicle use.

This is a list of United States Code sections, Statutes at Large, Public Laws, and Presidential Documents, which provide rulemaking authority for this CFR Part.
